GATE-HINGE.

SPECIFICATION forming part of Letters Patent No. 504,450, datedSeptember 5, 1893. Application filed September 18, 1891. Serial No.406,110. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES M. LAMB, a citizen of the United States,residing at Adrian, in the county of Lenawee and State of Michigan, haveinvented a new and useful Improvement in Gate-Hinges, of which thefollowing is a specification.

My invention relates to an improvement in gate hinges, intendedespecially for use in connection with a gate of the kind shown in thedrawings and it consists in combining with the pintlebar, slidingvertically in its hinges, a vertically adjustable stop on thepintle-bar, above one of the hinges, whereby the height of the gate maybe regulated.

In the accompanying drawings, forming part of my specification,-Figure 1represents a front elevation of the gate and hinges complete; and Fig.2, a perspective view of the lower hinge.

A represents a gate-frame, consisting of a rod bent to an approximatequadrangle one of the sides of which constitutes the pintle-bar for thehinges. As shown, the frame is braced by diagonal wires or rods 13 B,held at the corners by struck-up portions, t, of the frame, and isprovided with wire mesh C.

D is the lower hinge comprising an angleplate, the lower part- 5 ofwhich has an opening through it fitting loosely over the inner uprightside of the quadrangular frame A, being placed there in the process ofmanufacture of the frame, and-the vertical part r of which hasscrew-holes q to permit the hinge to be secured to a gate-post, and aseparate collar 10, also encompassing the inner upright bar of the frameand likewise placed in position in the course of manufacture of theframe, and provided with a set screw, 0, whereby it may be firmlyclamped to the upright bar referred to and turn with the latter while Iresting upon the horizontal parts of the hinge.

E is the upper hinge, consisting of a screwbolt at, having nutsm,whereby it may be passed through and secured to the gate-post, andhaving its outer end bent spirally, as shown at Z, to form an elongatedcollar for the vertical inner bar of the gate. This particular hingeforms the subject of a separate application by me for a patent, Viz.,Serial No. 461,328, filed February 7, 1893. Before placing the gate inposition the upper hinge E is inserted in the gate-post. The uprightinner bar of the gate is then introduced into the spiral part Z, andfinally the hinge D is secured to the gate-post by screws passingthrough the holes q. The set-screw 0 permits the gate to be adjustedWithin certain limits to the required height. Of course the hinges D andE may be transposed if desired; and their use is not confined to theparticular form of gate shown.

What I claim as new, and desire to secure I by Letters Patent, is-

1. In combination with the pintle-bar of a gate, a hinge secured to thegate-post and loosely encompassing the pintle-bar and a verticallyadjustable stop upon the pintle-bar above the hinge, substantially asdescribed.

2. In combination with the pintle-bar of a gate, a hinge secured to thegate-post and loosely encompassing the pintle-bar, a collar 10 upon thepintle-bar above the hinge, and a set screw 0 passing through the collarfor adjustably securing it to the pintle-bar, substantially asdescribed.
